I purchased a few roles of Ilford Delta 3200 from B&H in the fall of 2004.
Since that time the rolls have been stored constantly in a sealed freezer bag in my refrigerator. I no longer have the package, so I can't be sure what the film's expiration date was - but it probably seems reasonable to suspect it was in the 2006-2008 timeframe.
I finally have a subject that might call for some real speed (EI 1200 or higher) and was thinking of using the film. I know that keeping the film cool helps, but it won't affect exposure to cosmic background radiation. I will also be processing the film within several days after shooting.
Has anybody shot Delta 3200 that was 1-3 years out-of-date but carefully stored? What have your results been like?
